Description

Technical Field

[0001] The present invention relates to the technical field of knife sharpeners. Background Art

[0002] A knife sharpener is a tool used to sharpen knives. Traditional knife sharpeners are whetstones, which are generally large in size, and a whole piece of whetstone is used to sharpen the knife. However, with the development of society, knife sharpeners have evolved from traditional whetstones.

[0003] Knife sharpeners and whetstones are both used to sharpen knives. The difference between knife sharpeners is that: knife sharpeners are designed to make their appearance and functions more perfect;

[0004] When grinding with a traditional whetstone, the knife is placed almost flat, one hand holds the knife handle tightly, and the other hand presses tightly on the surface of the knife, grinding at a small angle between the knife and the whetstone;

[0005] The knife sharpener in the prior art includes: a shell and a sharpening rod arranged in the shell. The shell is provided with a handle. The user applies force to press the handle, vertically inserts the knife into the magic knife groove on the shell, and pulls the knife back and forth to perform the sharpening action. It is simpler and more convenient to use, and the appearance is more beautiful than the traditional whetstone.

[0006] However, in the prior art, since the knife sharpener is provided with a knife sharpening groove, the knife sharpening groove is easy to hide dirt, but it is not easy to clean;

[0007] The applicant has improved the knife sharpener in the prior art and filed the following patent application. Summary of the invention

[0008] In view of this, the present invention provides a knife sharpener.

[0009] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a knife sharpener comprises: a main body, on which a knife groove is formed; a knife sharpening rod, which is installed in the main body and protrudes or appears in the knife groove; a movable cover, which is slidably connected to the main body to open or close the knife groove; a guide column is formed on the movable cover, the movable cover is covered outside the main body, and the guide column is inserted into the main body to guide the movable cover to move linearly along the main body; convex wings are formed on both sides of the guide column for preventing the movable cover from deflecting when sliding, and wing grooves are formed inside the main body corresponding to the convex wings, and the convex wings are embedded in the wing grooves; a limiting member is provided on the main body to limit the movable cover from completely separating from the main body;

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] Knife sharpener, see Figure 1-4 As shown, it comprises: a main body 100, a knife groove 101 is opened on the main body 100, and a knife sharpening rod 200 is arranged in the knife groove 101. The knife is inserted into the knife groove 101 and pulled back and forth, so that the knife sharpening rod 200 sharpens the knife.

[0036] There are multiple knife grooves 101, and each knife groove 101 can be provided with a knife sharpening rod 200 of different structures, which can be divided into coarse grinding, fine grinding, fine grinding, etc.;

[0037] Alternatively, a knife sharpening rod 200 with different structures is placed in each knife groove 101, so that knives of different types can be sharpened.

[0038] The main body 100 is connected to a movable cover 300, which is opened and closed by sliding relative to the main body 100; the opening and closing actions here are to cover or open the knife groove 101. When the sharpener is not in use, the movable cover 300 is closed to cover the knife groove 101, which can prevent dirt from entering the knife groove 101, so as to keep the knife groove 101 clean and hygienic.

[0039] A sliding structure is provided between the main body 100 and the movable cover 300 , so that the movable cover 300 can slide smoothly relative to the main body 100 .

[0040] The movable cover 300 is installed on the outside of the main body 100, covering the main body 100 in the form of a cover; a guide column 310 is provided inside the movable cover 300, and the guide column 310 guides in a general direction and limits the movable cover 300 to move only in a straight line;

[0041] Correspondingly, the main body 100 is provided with a socket 102 for inserting the guide post 310 , so that when the movable cover 300 moves, the guide post 310 moves linearly in the direction of inserting and removing the main body 100 .

[0042] At the same time, in order to guide the movement of the guide column 310 without causing up and down deviation, a first limiting plate 110 is arranged above the guide column 310 in the main body 100. The first limiting plate 110 prevents the guide column 310 from tilting upward during the movement and affecting the movement.

[0043] During the movement of the movable cover 300, the thrust of the user may not be truly parallel to the moving direction of the movable cover 300, but may have a slight deviation. Therefore, during the movement, the movable cover 300 may not move smoothly due to the non-parallel force, and may deviate left and right.

[0044] In order to prevent the movable cover 300 from shifting left and right when moving, protruding wings 320 are formed on the two sides of the guide column 310. Similarly, a wing groove 120 is formed inside the main body 100, so that the movable cover 300 can be prevented from shaking left and right when moving.

[0045] The structure of the convex wing 320 and the wing groove 120 can also prevent the movable cover 300 from tilting upward. Figure 5As shown, the up and down directions correspond to the up and down directions on the paper, and the left and right directions correspond to the directions perpendicular to the paper.

[0046] That is, if the movable cover 300 moves linearly in the X direction relative to the main body 100 , the first limiting plate 110 can prevent the cover from tilting in the Z direction, and the cooperation between the protruding wing 320 and the wing groove 120 can prevent the cover from deflecting in the Y direction.

[0047] The wing slot 120 is located below the first limiting plate 110 .

[0048] In order to prevent the movable cover 300 from being completely separated from the main body 100 , a limiting member 130 is provided on the main body 100 .

[0049] The bottom of the main body 100 is provided with an opening 103, which is connected to the inside of the main body 100. The stopper 130 is inserted through the opening 103 from the bottom of the main body 100 and protrudes from the inside of the main body 100.

[0050] The guide column 310 is provided with a first abutment position 311 and a second abutment position 312 that cooperate with the limiting member 130 ; when in the closed state, the limiting member 130 abuts against the first abutment position 311 , and when in the open state, the limiting member 130 abuts against the second abutment position 312 .

[0051] A movable groove 313 is provided at the bottom of the guide column 310. The movable groove 313 is provided for the embedding of the limit member 130 and serves as a clearance groove when moving. The end walls at both ends of the movable groove 313 constitute the first resistance position 311 and the second resistance position 312, so that the guide column 310 will not completely separate from the main body 100.

[0052] Through the above-mentioned multiple auxiliary sliding structures, the movable cover 300 can slide steadily and smoothly.

[0053] In a further technical solution, in order to enable the movable cover 300 to be well positioned after sliding, that is, to be well positioned in the open state and the closed state, a first card point 140 and a second card point 150 are provided inside the main body 100, and the first card point 140 and the second card point 150 are provided on the inner bottom wall of the main body 100; the guide column 310 is formed with an elastic card plate 314 at the beginning of the movable groove 313, and a card protrusion 315 is formed on the elastic card plate 314.

[0054] See also Figure 5-6As shown, when in the closed state, the locking protrusion 315 is locked in the first locking point 140, and when in the open state, the locking protrusion 315 is locked in the second locking point 150. In this way, the movable cover 300 can be positioned relative to the main body 100 to prevent the movable cover 300 from sliding due to the force vibration of the sharpener or some external force during the sharpening process; or to prevent the sharpener from automatically opening during the movement.

[0055] In a further technical solution, the limiting member 130 includes: a mounting plate 131 level with the bottom of the main body 100 and an embedded portion 132 protruding upward from the mounting plate 131 and interacting with the guide column 310, and an undercut 133 is formed on the circumferential surface of the embedded portion 132, and the inner wall of the opening 103 forms an inclined surface; the limiting member 130 can be directly inserted into the main body 100, and the installation is very simple and convenient, and the mounting plate 131 is level with the bottom of the main body 100, which can ensure that the main body 100 can be placed stably; and the undercut 133 is provided to prevent the limiting member 130 from withdrawing.

[0056] The installation direction of the limit member 130 on the main body 100 is perpendicular to the moving direction of the movable cover 300. If there is no limit member, the first clamping point 140 and the second clamping point 150 are limited to the clamping protrusion 315. In this way, if the force used to pull the movable cover 300 is slightly large, the movable cover 300 may be completely separated during the opening process, and the clamping protrusion 315 may be damaged. After the limit member 130 is set, this problem can be well solved.

[0057] In a further technical solution, a bottom cover 160 is provided at the bottom of the main body 100, and the bottom cover 160 can cover the bottom of the main body 100 and cover the opening 103 at the same time to prevent the limiter 130 from detaching; and preferably, the bottom cover 160 can be an anti-slip cover or an anti-slip pad, which can play a good anti-slip role.

[0058] The outer wall of the main body 100 is formed with a slide groove 104, and the inner wall of the movable cover 300 is correspondingly formed with a slide bar 330, and the two cooperate with each other.

[0059] In a further technical solution, a fixing cover 400 is further installed on the main body 100 .

[0060] See also Figure 2As shown, the main body 100 is roughly in the shape of a long strip, and the top is arranged in an arc shape, and the knife groove 101 is provided on the right side of the main body 100, and the left side is used for the user's hand support when sharpening the knife, so as to apply force to stabilize the knife sharpener; then the fixed cover 400 is installed on the left side of the main body 100 and does not cover the knife groove 101, and the movable cover 300 is installed on the right side of the main body 100 opposite to the fixed cover 400, and slides in the direction of approaching or moving away from the fixed cover 400 to realize opening / closing.

[0061] Furthermore, the knife grooves 101 are provided in plurality, and bone positions are provided inside the main body 100 corresponding to the knife grooves 101 , and the knife sharpening rod 200 is installed in the bone positions and protrudes from the knife grooves 101 .

[0062] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
